Detailed explanation-3: -By banning new production and use of CFCs, the Montreal Protocol eliminated a significant contributor to climate change, avoiding a potential additional global temperature increase of 0.5 to 1 degree Fahrenheit by 2100.

Detailed explanation-4: -Once widely used in the manufacture of hundreds of products including aerosol sprays, such as blowing agents for foams and packing materials, solvents, and in refrigeration, CFC production for such uses was banned under the Montreal Protocol in 2010.
